五年级下册家庭作业第二单元的作文语文

五年级下册家庭作业第二单元的作文语文全文共8篇示例，供读者参考篇1亲爱的老师和同学们:大家好!我是小明,今天我要和大家分享一下我在这个学期学习第二单元"经典诵读"时的一些感受。

我知道对于一些同学来说,背诵古诗文是一件很枯燥乏味的事情,但通过这次学习,我发现其实背诵古诗词并不像我想象的那么困难和无聊。

首先,我要说的是李白的诗歌。

老师让我们背诵了《静夜思》和《望庐山瀑布》两首绝句。

一开始我也觉得很吃力,因为古诗里有很多生僻字,而且许多词语的意思也不太好理解。

不过通过老师的耐心讲解和我们大家一起探讨,慢慢地,我开始体会到李白笔下的意境之美了。

《静夜思》用了很多很美的比喻和夸张的手法,把诗人对故乡的思念之情渲染得无比动人。

我最喜欢"床前明月光,疑是地上霜"这一联了,把皎洁的月光比作洒在地上的白霜,使读者仿佛置身于秋夜的露重花残之景。

而"举头望明月,低头思故乡"则道尽了游子在异乡时对家乡的无限眷恋。

至于《望庐山瀑布》,则是以雄浑有力的笔触,生动形象地描绘了庐山瀑布的壮丽景象。

"飞流直下三千尺,疑是银河落九天"这句诗把瀑布形容得那么雄伟磅礴,简直就像是天上的银河倾泻而下一般。

读到这里,我仿佛看到了那汹涌澎湃、气势磅礴的万丈瀑布,令人震撼莫名!除了李白的诗,我们还学习了陆游的名篇《示儿》。

这首词描写了一位父亲对儿子的教导和期望。

"人有悲欢离合,月有阴晴圆缺,此事古难全"这几句话启发了我们要有宽阔的胸襟,正视生活的无常,做好应对变故的准备。

而最后的"惟愿孩儿归来,等闲识尽千般风情雨露"则表达了作者希望儿子将来游学归来后,能成为一个博学多识、见多识广的人。

通过背诵这些优秀的古典名作,我不但锻炼了记忆力,而且也开阔了视野,增长了见识。

在理解诗词的过程中,我们还一起探讨了不少有趣的典故、历史人物和事件,让我对中国悠久灿烂的文化有了更深入的认识。

About Flash................................................................................

Production of multimedia content using FlashDepartment of Electronics and Computer Science, University of Southampton1. AbstractMacromedia Flash is one of the most powerful web authoring tools available to web designers today and is used to produce animated and still graphics. However, because of the poor use of Flash animations on the Internet, Flash has acquired a reputation for poor usability. Macromedia itself Macromedia itself and other individuals have produced tools and documentation to help designers make the most out of Flash have now published many usability tips. If these are followed, good multimedia content can be produced which is usable to others.ContentsKeywords ............................................................................................. 1 Introduction .......................................................................................... 1 Background .......................................................................................... 2 Research.............................................................................................. 2 About Flash ..................................................................................... 3 Flash Usability ................................................................................. 3 Alternatives to Flash........................................................................ 4 My Film ............................................................................................ 4 Conclusions.......................................................................................... 9 References......................................................................................... 102. KeywordsMacromedia Flash, Multimedia Content Creation, Animation Graphics, Sound, Video,3. IntroductionThe aim of this paper is to look at multimedia content produced by Macromedia Flash. Flash has become very popular over the past few years; 474 million Internet users use it today. In this paper I research into how Flash is used by developers today and why to give a background into the use of Flash. The advantages and disadvantages of Flash as a multimedia content creation tool are discussed to help developers to decide if Flash is a suitable tool for their project. A number of usability tips for Flash have been put together by a number of individuals, which it is recommended to follow if a usable Flash application is to1be made. I will research into these and outline them. I will also research briefly into alternatives to Flash. To fully understand how to create multimedia applications with Flash, I made a small movie of my own in Flash. I will describe the nature of my film and how it was created. Finally, I will evaluate my film and report my findings and give a summary of my experiences using Macromedia Flash.4. BackgroundFlash was first introduced in 1996 and was known as FutureSplash Animator and run by a company called FutureWave. It was used to play back animation on web browsers through Java. The company decided to sell off their technology due to financial difficulties, they tried Adobe who turned them down, but were soon bought by Macromedia. FutureSplash Animator became Macromedia Flash 1.0. There are 2 main components to the Flash software, which are: • Flash Editor – which is used to create the graphics and animation that make up the end movie • Plug-in or Flash Player – which is used by web-browsers to display the Flash movie Flash can be used to create movies, which incorporate graphics, sound and animation. These movies are generally placed on web sites on the Internet. The main reason web designers use Flash is because it provides a good online user interface, allowing visitors to interact with a web site. Also, animation is known to have a tremendous effect on human peripheral vision and therefore is a good way to relay information to people. Unfortunately, bad use of Flash on web sites has left Flash with a tarnished reputation. Most people either love it or hate it. Even though Flash is very popular on the Internet, many people find the Flash content unusable and annoying. The main arguments for Flash content being unusable are as follows: • The majority of Flash content is unnecessary and gratuitous • Content is usually built once and then not updated regularly • Content usually follows the established standards for Web content5. ResearchFirstly, it is important to look at reasons why and why not to use Flash as a way of conveying information on the Internet. These reasons are outlined below. Advantages of using Flash: • Flash films are browser independent; therefore they can be viewed with any browser, so is not limited. • Designers are able to control colours, fonts and resolution quality, and so can make their films to their needs. • As vector graphics are used, films can be scaled without it affecting the image resolution and objects will be smaller than their bitmap equivalents.2• •Animated and interactive films can be produced with sound, which will be more appealing to visitors, and get information across more easily. Flash software is very powerful, well supported and updated frequently.Disadvantages of using Flash: • Flash is quite a hard piece of software to learn, it may take developers a significant amount of time to learn to use the flash development environment • A plug-in is required to view Flash films, so not all machines will be able to view Flash films. • Flash does not have a user-friendly interface and it not intuitive for designers, and therefore might take designers longer to produce multimedia content. • Printing Flash movies results in poor text quality. • Search engines are unable to read Flash movies, so they do not show up. • It takes longer to create a Flash website than the usual HTML ones.About Flash Flash files have the .SWF extension. These files combine code, media and data into a format that is compact. These are loaded using a steaming model, where the first few frames become available to view once. The files are also cached, so that they can be retrieved again locally, saving time. Video and audio are streamed, which means that MP3 content can be dynamically loaded and player, and that full-motion films can be added. The Sorenson Spark Codec is used for high quality playback with low bandwidth. Flash uses a compressing/decompressing model to help lower network costs. Developers can compress their code when publishing the movie, and when a user wants to run this, it is decompressed on the user’s machine at runtime. Flash Usability One of the main problems with Flash is that it is known to have poor usability. Some usability tips have been produced by individuals. Macromedia’s Flash Usability tips: [/software/flash/productinfo/usability/tips/] • Remember user goals • Remember site goals • Avoid unnecessary intros • Provide logical navigation and interactivity • Design for consistency • Don’t overuse animation • Use sound sparingly • Target low-bandwidth users • Design for accessibility • Test for usability3Alternatives to Flash Flash is not the only development tool available to create multimedia content. A brief discussion of alternatives is presented below. Synchronized Multimedia Integration Language (SMIL) – this is a mark-up language (XML) which is used to write interactive multimedia content. Developers can define the temporal behaviour of their content and the layout of this on screen. Video and audio can be streamed with together with other media types. Scalable Vector Graphics (SVG) – this is a language used to describe two dimensional vector based graphics. It allows for images, text and vector and vector graphic shapes. The Document Object Model (DOM) includes full XML DOM, which allows for effective vector animation via scripting. My Film I used Macromedia Flash to create a small animated film which is to be placed on my university website. I had only ever encountered these types of films on the Internet, but never made one of my own. I also had never used Flash before, so it was a new experience. My film is titled “How to Turn a Geek into a Super Stud”, and shows through animated and still graphics how you can make a geek into a super stud! It can be viewed at /~mkg100 There are some important concepts that need to be understood before starting with Flash, these are described below. • SYMBOLS – these are graphics that have been created by using the drawing tools, and can be used over and over again within the film. • LAYERS – these can be thought of as transparent sheets that are placed on top of each other. Objects can be drawn on one layer without affecting objects in other layers. • FRAMES – displays the contents of I second of the film; a film is made of a series of frames. • KEYFRAMES – these are frames where changes in animation occur. The first frame in a frame is automatically a keyframe. • TIMELINE – shows the frames in all the layers of the film, and what events are occurring in the frames. The film starts of with the opening screen which shows the title, with a moving flashy yellow border, and a button, which when pressed will start the main part of the film. These three objects are placed in their own layers (I made a new layer for each). To place the title on screen, I created a layer called text (Insert ! Layer) and had to use the Text tool from the drawing tools, which works pretty much the same way as the ones found in other programs. You just have to enter the required text into the4box, and change the font size, type and alignment, as you so please. I also inserted a keyframe at frame 25 (Insert ! Keyframe), as this is the last frame that the text appears in. To insert the keyframe, you have to have that particular frame selected from the timeline. I created a new layer for the yellow flashy border, which was created by using keyframes and motion tweening. Motion tweening is used to change the size of objects or rotate them in an animated manner. I placed a keyframe every 5 frames, up to frame 25, and changed the size of the border in each one by transforming the shape (Window ! Inspectors ! Transform), or you could use the re-size option in the drawing tools to change the size. I then inserted the motion tween in each keyframe (Insert ! Create Motion Tween), which makes the border move from one size to the other. These 25 frames run continuously until the arrow button is pressed. This was achieved by selecting frame 25 in this layer and modifying the frame properties (Modify ! Frame ! Actions tab). I added a ‘Go to’ action and specified the frame to ‘go to and play’ scene 1, frame 1; the beginning of the film. The red arrow was also created in another layer, using the drawing tools, and was then turned into a button (Insert ! Convert to Symbol ! Button). When the cursor is placed over the button, the arrow increases in size. To do this you have to select the arrow button and then edit the object (Edit ! Edit Selected). This brings up a new scene with just the button in it. The timeline at the top of the screen has frames for ‘up’, ‘down’, ‘over’ and ‘hit’. You need to edit the button design in each frame depending on what you want the button to do when the corresponding actions occur. In this case, in the ‘over’ frame I drew an enlarged arrow by using the re-size tool. When the arrow button is pressed, the film jumps to the next screen, which starts in frame 30. The button performs this action by editing the buttons properties (Modify ! Instance ! Actions tab). I added a ‘Go to’ action and specified the frame ‘go to and play’ at as frame 30. Again I added a keyframe at frame 25, as this is the last frame for the arrow. There is another layer in this screen, which displays the background. In this instance the layer is empty as the background is white. The next scene shows the geek and ‘Mandy’s Geek Transformer’ machine, which starts from frame 30. The background is now a sea blue colour, which I created by drawing a large box with the drawing tools to fill the screen. The background layer must be the layer at the bottom so that all the other objects can be place on top of it. I created a new layer for the geek and placed a keyframe at frame 30. In this frame I used the drawing tools to create the geek. I then used drawing tools to create the speech bubble and then added a text box inside this to add the words. I also wanted some to be played at this frame; the geek saying “hello, my names Colin”. I had recorded some voices earlier with my microphone onto my5computer. I then imported this sound into Flash (File ! Import ! select sound file). I wanted the sound to be played at frame 30, so created a new layer for this sound. I then edited the frame properties to play the required sound file (Modify ! Frame ! Sound tab ! select file from drop down box) at this frame. Then I added another keyframe at frame 45, as this is the frame in which the transformer machine enters the film. I wanted the film to stop here until the button on the machine is pressed. Therefore, I set an action to frame 45 in the geek layer called ‘Stop’. This causes the film to stop at that frame until another event is triggered; in this case, the red button on the machine is selected. The machine is also drawn in a new layer and is created with the drawing tools. The title is drawn using the text facility. The red circle on the machine is a button whose action is to ‘go to and play’ at frame 50. At frame 50, I placed keyframes in the geek layer and the machine layer, as I wanted the objects in this layer to be displayed on screen but I deleted the geek’s speech bubble, as it was no longer required. I then created another layer, which starts at frame 50. This layer contains the rays that shoot out of the machine when the button is pressed and the ‘zap’ graphic. I drew the rays and zap with the drawing tools and then inserted another keyframe in this layer 3 frames down, frame 53, and used the re-size tool to reduce the size of the rays. I then used motion tweening to make the ray’s change in size on an animated way. I repeated this until frame 71, increasing and decreasing the size of the rays each time, with motion tweening between each. This was to give a shooting rays effect. I moved the ‘zap’ graphic in each of these keyframes as well with the aid of the arrow tool from the drawing tools. During the zapping, the geek shouts “Nooo!” which occurs from frame 50 to frame 82. Again I used the drawing tools to create this.After the zapping has finished the film has reached frame 83. The layer that contains the machine is no longer needed, so there are no frames for this layer anymore. In the geek layer, the geek has a speech bubble beside him, which was made by the drawing tools. The only layers active at this point are the one with the geek in it and the background.6Now the geek transformation begins!In this scene, which starts at frame 98, I entered a keyframe and deleted the glasses from the geek and added a text box, both changes were made to the geek layer. I also drew some new eyes with the drawing tools and placed them over the old eye. I left this scene and all the others after this on for 15 frames in order to give people time read the text and note the difference in the geek.This scene starts at frame 113, where I placed a keyframe. I deleted the spots from the geeks face and entered new text into the text box.Another keyframe was placed at frame 128 in the geek layer. I drew another mouth using the drawing tools and placed it over the old one. I also edited the text in the text box.I placed another keyframe at frame 143 in the geek layer. I deleted the excess hair from the nose and ears with the aid of the eraser tool from the drawing tools. I then re-drew the hair using the paintbrush tool. Again, I edited the text.7This keyframe was added at frame 158 in the geek layer. I used the drawing tools to change the shape of the face and changed the text.A keyframe was inserted at frame at 173, and again drawing tools were used to change the shape of the body.This keyframe is at frame 188 and I used the fill tool to change the colours of the clothes.This is the last scene and the keyframe was inserted at frame 203 and I used the text tool to edit the text. I also created a button using the drawing tool to draw it. I then added an action to the button, which is ‘go to and play’ frame 1, which is the beginning of the film. I also added some sound to this frame, which says “hey baby!”, by changing the frame properties.8This concludes my film. The final step is to convert the Flash file into a movie so that is can be viewed in Flash players (File ! Export Movie ! specify file name and Save).6. ConclusionsI found Macromedia Flash a very powerful tool. It allowed me to draw pictures and make simple animations quite easily. I found Flash relatively easy to use when drawing basic pictures and animations, but it started to get very complicated when I attempted to produce more advanced animations. In my film, where the rays bombard the geek, I tried to animate the geek so that it looked like he was getting electrocuted. Unfortunately I was unable to do this. When I animated the geek Flash automatically turned the geek into a symbol, which meant that I was unable to change the appearance of the geek after this. This meant that I could not finish my film as the last part of the film is concerned with editing the appearance of the geek. I therefore decided that it would be more beneficial to not have the animated geek, but to have the appearance of the geek change. Flash has a large variety of tools, but there are far too many to learn. It would take a tremendous amount of time to fully learn all the tools and functions available. Also, as there are lots of things that Flash can do, it is hard to know exactly what can be done, as lots of time would be required to learn everything. It can also get very confusing knowing what does what. There are a number of tutorials that are available in the Flash software, which cover: • Basic drawing • Concepts • Buttons • Simple animation • Streaming audio These tutorials are extremely useful as you can learn enough to make a simple film and are very easy to follow. There are step-by-step instructions on how to make objects and lots of screen dumps so you can check if you are doing the right thing. Flash also has a good Help, where you can search on keywords. The concept of layers in Flash is extremely useful as it helps to organise objects. You can also colour code the layers, which helps to show which objects belong to which layer, especially when there are a lot of objects. It is also possible to lock layers, which is useful when you do not want to accidentally change objects, Making simple animations is quite straight forward, especially since there is a whole tutorial on it. But it is a lot harder to make complex animations, as there is no extra help. I found Flash quite easy to use, but to fully master it would take a lot of time and energy. It is very good for making multimedia content, as it allows you to incorporate graphics with animation and sound without any programming knowledge. It can annoying sometimes as it can quite awkward to draw objects as you want and it could benefit from more advanced drawing tools. Also, more help is needed on how to produce animations.97.

人教版五年级数学上册《积的近似数》小数乘法PPT课件(5)

0.8×0.9(得数保留一位数)。 0.8×0.9＝0.72＜≈0.75
1.7×0.45(得数保留两位数)。
1.7×0.45＝0.765≈018 5 45 0.7 6 5
0.8×0.9＝0.72≈0.7 1.7×0.45＝0.765≈0.77
一个大楼有21层，每层高2.34米，这栋大楼约高多少米？得数保留整数。
注意事项：要看清楚题目的要求；所要保留数位的末一位或末几位是0，不能划去。
三、巩固练习
1.计算下面各题。
0.8×0.9 ≈0.7
1.7×0.45 ≈0.77
（得数保留两位小数）
（得数保留一位小数）
0.8 × 0.9
0.7 2
2＜5，舍去2，保留一位小数
0.4 5 × 1.7
315 45 0.7 6 5
家庭作业：练习三第1题第（1）小题、第2题。
怎样求积的近似数？
用四舍五入法来求积的近似数，得数要保留一位小数。所以，要看十分位，十分位的后面是0，它比4小。所以，要舍掉，约等于2.2亿个。
怎样求积的近似数？
四舍五入，求十分位就要看百分位，求百分位就要看千分位。同时，要看后面的那个数，是否大于5或者小于5。大于5或者等于5，就要把它入上去；小于 5，就要把它舍掉。
近似数使用的范围真广。
在实际应用中应该根据需要按四舍五入法保留一定的小数位数求出积的近似数。
一种大米的价格是每千克3.85元，买 2.5千克应付多少钱？
3.85×2.5=9.625(元) 3.85×2.5≈9.63(元)
数学，源于生活，还要服务于生活。
在解决实际问题的过程中，一定要注意数学的灵活性，认真观察，按实际需要求出积的近似数。
